Fix image type with absolute urls

Absolute URLs in entity properties were rendered with a heading '/' with the `image` type:

```yaml
fields:
- { property: 'thumbnail', format: 'image'}
```

If an entity contains a `thumbnail` property with the following absolute URLs: `http://example.com/img/my_image.png`
it previously rendered:

```html
<img src="/http://example.com/img/my_image.png">
```

This behavior is fixed for the following absolute URLs "patterns":

- http://example.com
- https://example.com
- //example.com
